Hello, as I was trying to login to my website, I got this error: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. Please what does this mean and how do I resolve it? Thank you
